DRUll/lr-STAND.

SPECIFICATION forming' part of Letters Patent No. 706,937, dated August12, 1902.

Application filed April 25,1901. Serial No. 57,435. (No model.)

To LZZ whom, t may concern:

Beit known that'LALBERr B. HELLENKAMP, a citizen of the United States,and a resident of Cleveland, inthe county of Cuyahoga and State of Ohio,have invented a new and Improved Drum-Stand, of which the following is afull, clear, and exact description.

This invention has for its object to provide a novel simple device forsupporting a drum at any desired height from the ground or floor whereonit rests and afford lneans to readily adjust parts of the stand, so asto give the drum carried by the stand any desired inclination, a furtherobject being to provide a drum-stand which is light, strong, neat inappearance, and is contractible in its legs, that are connectible with adrumhead-hoop at one end of each leg and adapted for secured locationwithin the space bounded by the provjecting rim of the drum-hoop.

The invention consists in the novel construction and combination ofparts, as is hereinafter described,and defined in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indi-` catecorresponding parts in all the figures.

Figure lis a side view of the improved stand and of a drum held thereon.Fig. 2 is sectional side view of a portion of a drum and apartly-sectional view of a leg of the improved stand connected with thedrum-hoop. Fig. 3 is a side view of one of the stand-legs differing inlength from the one shown in Fig. 2. Fig. 4 is a rear View of the drumand of the supporting-stand therefor in folded condition. Fig. 5 is anenlarged side view of a portion of the drum-hoop and of a novel detailof the stand and which when not in service is held upon the hoop, andFig. 6 is an en? larged partly sectional side view showing means forholding the legs of the drumstand in folded condition.

The improved stand in brief comprises three legs having telescopingmembers which permit their individual extension and also theircontraction to a length which adapts them to be disposed in triangularorder upon one head of the drum when not in use as a stand. Furthermore,provision is made to removably secure one end of each leg upon a hoop ofthe drum near its free edge. In arranging the stand for use the legs aresuitably extended and crossed, so as to contact with each other, saidlegs being held connected as a tripod by a suitable securing device.

The drum may be of any preferred construction and, as usual, is providedwith heads held in position at the ends of the drumshell A by cylindrichoops A', that are drawn toward each other and held in clampingadjustment by the bolts A2, that are furnished with hooked heads andnuts on their ends for engagement with the edges of the hoops, as usual.V

The three legs which are coacting members of the improved drum-standeach consist of a plurality of tubular sections formed of any preferredmetal. Two of the legs for the stand are individually composed of threesections 10 l()a 10 and the third leg of live sections 11 11a 11b llc11d, that give said leg increased length. The tubular sections 10, whichare similar parts of the two shorter legs, are of such internal diameteras to adapt them to respectively receive a middle section 10", and saidmiddle section for each of the paired legs in turn forms a casing forthe upper leg-section l0b when said parts are slid together, so as toshorten the legs as occasion may require. The three sections 10 10 l0bof each of the similar, legs have close-fitted engagement one within theother,respectively, and to adapt them for convenient insertion at theirengaging ends the extremities of the leg-sections which entercomplementary ones of greater diameter are tapered suiciently to permitthis to be readily eected, and it is to be understood that theinsertible end portions of the leg-sections of the three legs formingthe improved drum-stand. are tapered, as clearly shown at a in Fig. 2.Each tapered end a of a leg-section is longitudinally slitted a shortdistance, so as to render these end portions slightly resilient, andeach of the slitted ends may be slightly increased in diameter bycorrespondingly spreading the two Walls formed by the oppositeslits a',which will afford such frictional contact between the split ends andtubular leg-sections that receive them as to require some manual forceto slide the leg-sections one within the IOO other, whereby accidentalcontraction of the length 'of either leg is prevented.

The ends of the leg-sections 10 that are lowermost inservice have atapering point b formed on each one, which should be of metal hardenough to insure durability, and

at the open ends of each of the leg-sections 10 10 a peripheralreinforcing-rib c may be produced, which affords finish thereto as wellas strength. The normally upper section 10b of each of the shorter legsand which has a close sliding iit within a .respective middle section10Zt may be advantageously formed of tubular materiall to render thesame light without impairingits strength, and at the end opposite thatwhich enters the leg-section 10a a headpiece d is formed or secured,from which projects the arm CZ, terminating in a threaded bolt end d2.

The leg composed of the telescopingsections 11 11QM 11h11c 11d dierssomewhat in construction from Athe pair of legs that have beendescribed, as will be now explained.

The lower leg-section 11 is similar in size and form'to the leg-sections10 and terminates in a tapering end b for non-slipping engagement with afloor or the like. The legsection 11a, which is placed within the' upperend of the section 11, may be of reduced length as compared with theother leg-sections, and the end of the section 11b exterior of thelegsection 11a is hinged upon the adjacent end of the leg-section 11C,as shown atf in Figs. 1 and 2. In the hollow leg-section 11c thelegsection 1ld is held to slide, and, as shown in Fig. 2, the insertibleends a of the leg-sections 1la and 11d are tapered and longitudinallyslitted to adapt them for proper frictional engagement within theleg-sections into which they are inserted, as before mentioned. At thenormally upper end of the leg-section 1ld a headpiece d is formed orsecured having a lateral arm d' thereon, terminating in a threaded boltend d2, thisdetail being similar to the heads d on the paired legshereinbefore described.

An adjustable clamp is provided for each leg of the drum-stand, and, asshown in Fig. 3, each of the clamps which are to engage with the upperends of the leg-sections 10b, respectively, comprises a U-shaped blocke, perforated laterallyin one leg and threaded therein to receive thethreaded bolt end d2, which effects a secure rockable connection of theclamp member e upon the headpiece d at one side thereof. An L-shapedclamp member or block e' is adjustably secured upon the outer member ofthe U-shaped block e by an adj usting-bolt e2, having a right-handthread on one end and a left-hand thread formed on the opposite end,said threaded ends engaging within correspondingly-threaded perforationsin the blocks e and e', and, as represented, an angular formation c3 isformed at the center of the bolt-body c2 to aord means for convenientlyturning the bolt with a suitable tool.

It will be seen that the adjustment of the bolts e2 affords means forsecuring the clamping devices held on the upper ends of the stand-legsin place upon the lower hoopof a drum, as shown in Figs. 1 and 2, bygripping the same transversely, and in arranging the clamps foreffective service they are evenly spaced apart upon said hoop A', asshown in Fig. 4. The legs when secu red upon the dru mhoop A arerelatively disposed so as to position the two shorter ones oppositelyand the longer leg intermediately and at an equal distance from theshorter legs.

The leg-sections 10 10 10b of the `shorter legs are extendedof an equallength, and in the middle section 10a of each of said legs a transverseperforation g is formed at an equal distance from the point b on the endof each section 10. The remaining leg is also perforated in its section11a at a point g, which will dispose said perforation close to the likeperforations in the leg-sections 10a.

A three-limbed coupling 12 is furnished to hold the legs of the standsecurely joined together when it is erected, and, as best shown in Fig.5, said coupling comprises three screwbolts h, that radiate from acommon center, where they are integrally joined together, and thescrew-bolt formations are spaced apart an equal distance. Upon eachscrew-threaded limb or bolt h a preferably winged nut 12a is screwedafter thebolt-bodies are properly engaged with the leg-sections 10a and11a. The longer leg is now extended by outward movement of its sections,so as to permit the lower section 11 and the next section 11a, which isconnected therewith, to incline su liiciently so as to dispose the pointb of the lower section 11 forwardly and nearly in a vertical plane Withthe advanced lower portionof the upper drum-hoop A', as is clearly shownin Fig. 1. The coupling device is now connected with the three legs ofthe stand by insertion of a screw-bolt h through the perforation g in anappropriate leg-section, when the winged nuts 12a are removed, and saidnuts by their screwed engagement with the end portions of thescrew-bolts which project outside of the legs and the clampingadjustment of said nuts serve to draw the three-legs close together in asubstantial manner. The three legs arranged as described afford atriangular base for support of the drum, which by proper extension ofthe lower leg members 10` 10, and 11 may be properly spread apart andwill sustain the drum in a reliable manner.

It will be noticed that the two leg-sections 11c and 11d when vextendedfor proper support ot' the rear edge of the drum-hoop A are togetherdisposed in a nearly vertical plane above the joint f, and obviously theslidable adjustment of the uppermost section 11d into or out of theleg-sectionllC will correspondingly alter the degree of inclinationgiven to the heads of the drum.

The clamp provided for the upper end of l the leg-section 11(l issomewhat different from IOO IIO

those provided'to engage with the headpieces on the leg-sections 10b, asthe top clampingpiece e is longer than the clamping-pieces e',hereinbefore described, and, as shown in Fig. 5, the upper portion ofthe clamping piece or jaw e' is longitudinally grooved, as at e4, forreception of one bolt-body h and transversely channeled, as at e5, toreceive the central por tion of the three-limbed coupling-bolt. i Aplate-spring 12b is secured by one end on the outer face of theclamping-piece e', near its lower end, said spring extending its freeportion over the upper end of the limb to which it is attached.

When the coupling device l2 is removed from the legs of the drum-standto permit said legs to be contracted and folded upon the drumhead forconvenient transportation,said three-limbed coupling is introducedWithin the groove @fand channel e5 beneath the platespring 12b, so thatthe pressure of said spring will retain thethree-limbed coupling inplace, adapted for quick removal by proper handling, but not liable tobecome accidentally displaced. In Fig. 6 are shown tWo oppositeperforations U, diagonally formed in opposite corners of one of theblocks e, and it is to be understood that such diagonal perforations areformed in each U-shaped block Whereon a headpiece d Vof a stand-leg isheld to rock.

When the improved stand is to be held in contracted form on the drum atthe end to which it is secured, the sections of all the legs are slid soas to reduce theirlength sufiiciently to permit them to be disposedtriangularly, as shown in Fig. .4. Then the sections of each leg areextended sufficiently to enable the extremity of a pointed end b on eachleg to be introduced Within an opposite perforation b', and the legsWill thus be held from contact With the drumhead and will remain soadjusted until they are manipulated for release.

It Will be seen that the relative disposal of the telescoped legs asdescribed serves to retain them closely folded near the head of the drumin the recess afforded by the projected edge of the clamping-hoop A, andby this means they are protected against injury Wh en the drum iscarried or is seated upon the clamps that are engaged with the edge ofsaid hoop.

As the device either in folded or extended condition is light andsubstantial, as Well as comparatively inexpensive, and also isconvenient to erect or reduce to compact form for folded connection Withthe drum it is t0 support when in use, it Will be obvious that it isWell adapted for general use by those requiring a support for a drumWhile it is used as a musical instrument.
